Part Number: TPS6594-Q1
Other Parts Discussed in Thread: SK-TDA4VM, TDA4VM, TPS6594EVM

Dear TI experts,

My customer is now drawing schematic based on SK-TDA4VM.

I saw that 2 PMICs in BOM. Could you confirm that these 2 PMICs are the latest and confirmed part for TDA4VM?

(P)TPS65941213RWERQ1
(P)TPS65941111RWERQ1

If you have a plan to change these PMICs, please let me know.

And here is another question, Do you have GUI tool or other program for dumping register of TPS65941213 and TPS65941111? My customer needs it for comparing register and customized programming.

(I cannot find any programs in TPS6594EVM product page.)

How about the jig or EVM for GUI program? Can I get it?

+ And one more question, They could not see any output on PMIC on their own PCB. on the other hands, They Could see the outputs using TPS6594 EVM.

Is there any difference between PMICs of EVM and IC sample from TI.com? Should I control or write register for the purpose?

I attach 2 top markings of PMICs from TI.com

Please check these issues. Thanks.

Best regards,

Chase

Dear TI experts,

I posted same question on Processors Forum. Please refer the link below; I post same question on Power management forum just in case.

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1358810/sk-tda4vm-please-confirm-2-pmic-parts

My customer dumped register of their PMICs both their own PCB(samples from TI.com) and TDA4 EVM

Comparing these 2 registers, It has little differences,

I want to know that these differences are known issue or something is wrong.

And one more question, the samples from TI.com have the marking as above. I want to know that the ICs which marking are like the picture below should have initial register settings above.

or, Could you provide register setting which is suitable for TDA4 EVM? It will be very helpful to my customer.

Best regards,

Chase

Since this is already being worked in the other forum thread, I don't this thread is needed.

Agreed?
